lposition `for writing.r Means are provided for quickly and easilythrowing the attachment in or out of operation. The holder is adjustableto receive envelops of various The invention is illustrated in theaccompanyingdrawings, in which Figure 1 is a perspective view thereofremoved from the typewriting machine. Fig. 2 is a vertical cross sectionshowing the attachment applied to the carriage of the machine. Fig. `3is a detail of one of the brackets which support the device on thecarriage. Fig. 4 is a 'detail in top plan of the rear part of thedevice.

Referringispeciiically to the drawings, A indicates the carriage of thetypewriting machine, B the platen, and C the paper guide. The deviceforming the subject of this invention is mounted upon the carriage andis movable there-with.

The niain frame of the envelop holder is indicated at 4, comprisingparallel bars having upright portions at the rear end connected byacross bar, forming an angular traine on which the other parts aremounted. 'lhis frame is supported by hinged brackets ,consisting ot'upper portions 2() screwed into the under side of the bars, 4, and lowerangular portions 21 which are hinged to the upper portions, as at 22.The lower ends of the parts 21 are arranged to fit in holes in the sidebars of the carriage, to support the attachment upon the saine. Thehinges 22 allow the frame toi rock to a limited extent, the hinges beingsuuiciently tight so that the attachment will stay as set. The rockingreferred to throws the attachment in or out of operation as will behereinafter described.

At 5 are indicated angular side bars the free ends of which extendinwardlv through l takes the Specification of Letters Batent.

where they are fixed by set screws 23, S0 that said side bars can beadjusted'in or out and set t'o hold envelops of any length..

Top bars are indicated at 10,'having at the rear endsdownwardly-extending portions which are yieldingly clasped under springstrips 25 secured tothe cross piece of the frame 4, and said bars can beraised or 10W- ered to accommodate envelops of various heights. At theirfront ends the bars are provided with stops 10a which act to engage andhold the first envelop at the upper edge thereof. l l

Mounted in bearings in the front ends of the bars 4 is a shaft 12 whichhas at its ends friction rollers 8 which, when the device is inoperation, bear upon and are rotated by contact with the platen of themachine. The shaft also carries releasing devices, each of whichconsists of a disk 18 havingradial iingers 19, and the releasing devicesare preferably located on the shaft adjacent to the ends of the bars 4.'Ihe ends of said bars have on their u per side projections 26 againstwhich the rst envelop stops.

To advance the envelops toward the re# leasing devices atthe front ofthe arms,'a plate 7 is provided, resting upon the horizontal portions ofthe bars fi and supported at the ends bythe side rods 5 which fitinslots 7 a in the ends of the plate. On the rods, between the plate andthe inwardly-extending rear ends of the rods, are coiled springs 7.1,which press vagainst the plate, and tend to force 4the saine forwardly.

The envelops are placed in the frame formed by the hars 4, 5 and 10,with the first envelop,'thatis, the one at the front, bearingagainst-the projection 26 andthe stops 10, and with the plate 7 pressingagainst the bunch. The length of the fingers 19 is such that they willjust reach the lower edge of the Vfirst envelop, that is, ,the oneagainst the projections 26. The wheels 8 being in frictional contactwith the platen, turn of the latter causes the wheels and shaft 12 toturn, and the fingers 19 engage the first envelop and lift lthe same,carrying its loweredge over the projections 26 and beyond the ends ofthe bars 4, thereby releasing said envelop and allovng it to dropbetweenthe platen and the paper guide, whence it maybe fed to themachine in the usual way. The springs 7b advance the pack so thatanother envelop place of the one released "i-nreadiholes in the uprightiportions of the bars 4, l ness for the next operation.
